didnt realize y'all were talking about that brown-grey goo in the filter of our pumps. I've had that shit in my pumps since i created the blumat-muti-rez-waterfall-type-thingy. I change and clean the 35 gallon Brute trash can every refill, along with a quick rinse of the pump and filter. keep in mind this is the organic, hygrozyme/sm-90 only grow. in the chem nutes/clear rez grow, i dont see it.
just my observations.
